nginx rewrite實戰實例

　　本部份內容爲nginx生產環境中使用的場景示例。

域名跳轉（域名重定向）

示例1（不帶條件的）：
server{
    listen 80;
    server_name www.aminglinux.com;
    rewrite /(.*) http://www.aming.com/$1 permanent;
    .......
    
}

示例2（帶條件的）：
server{
    listen 80;
    server_name www.aminglinux.com aminglinux.com;
    if ($host != 'www.aminglinux.com')
    {
        rewrite /(.*) http://www.aminglinux.com/$1 permanent;
    }
    .......   
}

示例3（http跳轉到https）：
server{
    listen 80;
    server_name www.aminglinux.com;
    rewrite /(.*) https://www.aminglinux.com/$1 permanent;
    .......    
}

示例4（域名訪問二級目錄）
server{
    listen 80;
    server_name bbs.aminglinux.com;
    rewrite /(.*) http://www.aminglinux.com/bbs/$1 last;
    .......
}

示例5（靜態請求分離）
server{
    listen 80;
    server_name www.aminglinux.com;
    location ~* ^.+.(jpg|jpeg|gif|css|png|js)$
    {
        rewrite /(.*) http://img.aminglinux.com/$1 permanent;
    }
    .......  
}

或者：

server{
    listen 80;
    server_name www.aminglinux.com;
    if ( $uri ~* 'jpg|jpeg|gif|css|png|js$')
    {
        rewrite /(.*) http://img.aminglinux.com/$1 permanent;
    }
    .......
}

 

防盜鏈：

示例6
server{
    listen 80;
    server_name www.aminglinux.com;
    location ~* ^.+.(jpg|jpeg|gif|css|png|js|rar|zip|flv)$
    {
        valid_referers none blocked server_names *.aminglinux.com aminglinux.com *.aming.com aming.com;
        if ($invalid_referer)
        {
            rewrite /(.*) http://img.aminglinux.com/images/forbidden.png;
        }
    }
    .......
}

說明：*這裏是通配，跟正則裏面的*不是一個意思，none指的是referer不存在的狀況（curl -e 測試），
      blocked指的是referer頭部的值被防火牆或者代理服務器刪除或者假裝的狀況，
      該狀況下，referer頭部的值不以http://或者https://開頭（curl -e 後面跟的referer不以http://或者https://開頭）。
或者：

    location ~* ^.+.(jpg|jpeg|gif|css|png|js|rar|zip|flv)$
    {
        valid_referers none blocked server_names *.aminglinux.com *.aming.com aminglinux.com aming.com;
        if ($invalid_referer)
        {
            return 403;
        }
    }

 

僞靜態：

示例7(discuz僞靜態)：
location /  {
    rewrite ^([^\.]*)/topic-(.+)\.html$ $1/portal.php?mod=topic&topic=$2 last;
    rewrite ^([^\.]*)/forum-(\w+)-([0-9]+)\.html$ $1/forum.php?mod=forumdisplay&fid=$2&page=$3 last;
    rewrite ^([^\.]*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ $1/forum.php?mod=viewthread&tid=$2&extra=page%3D$4&page=$3 last;
    rewrite ^([^\.]*)/group-([0-9]+)-([0-9]+)\.html$ $1/forum.php?mod=group&fid=$2&page=$3 last;
    rewrite ^([^\.]*)/space-(username|uid)-(.+)\.html$ $1/home.php?mod=space&$2=$3 last;
    rewrite ^([^\.]*)/(fid|tid)-([0-9]+)\.html$ $1/index.php?action=$2&value=$3 last;
}

 

rewrite多個條件的而且：

示例8：
location /{
    set $rule 0;
    if ($document_uri !~ '^/abc')
    {
        set $rule "${rule}1";
    }
    if ($http_user_agent ~* 'ie6|firefox')
    {
       set $rule "${rule}2";
    }
    if ($rule = "012")
    {
        rewrite /(.*) /abc/$1 redirect;
    }
}
